Gets or sets a value indicating whether the site map node can be modified.
Assembly: System.Web (in System.Web.dll)
A SiteMapNode object is modifiable by default.
All nodes that are returned by the XmlSiteMapProvider are read-only, by default.
The Attributes, ChildNodes, Description, ParentNode, Roles, Title, and Url property mutators check the property before attempting to modify the property of a site map node. If the node is read-only when a mutator is called, the SiteMapNode object throws an InvalidOperationException exception.
